A TTORNEE UNITED STATES PATENT OFFICE;

STEPHEN G. PORTER, OF NEW- YORK, N. Y., ASSIGNOR TO THE PORT-O-PI-IONE CGRPORA- TION, OF ESOPUS, NEW YORK, A CORPORATION OF NEW YORK TELEPHONE APPARATUS.

Specification of Letters'Patent. Patented NOV. 13, 1917.

Application filed October 4, 1916. Serial No. 123,608.

To till whom it may concern:

Be it known that I, STEPHEN C. PORTER, a citizen of the United States, residing in the borough of Manhattan, city of New v York, county of New York, and State" of New York, have invented new and useful Imp movements in a Telephone Apparatus, of which the following is a specification. This invention relates to telephone ap- KJ paratus. and more particularlyto the receiving portion thereof, and has for its objeot to make it"possible to use the receiver either at the e313 "in the ordinary manner, or while stationarily supported in conjunc- 15, tion with an amplifier, "-2111 the latter event the userdoes not',have topick up the receiver at all, andthe incoming message may beaudible toothers in the room, whereas if the conversation is to be private the other 3 mode of use may be followed. These objects are attained bythe combination of a receiver and a'holder wherein the same may be placed in communication with an amplifier, "which latter is preferably embodied 5 with the holder in a form of low stand adapted to rest'upoh the desk or table.

*In the accompanying drawings:

lis a perspective view of the apparatus, with the receiver out of its cup; 'Fig.,;2 is "a vertical longitudinal section through the" stand and amplifier with the reee'iverqin place and partly in section and partly in'elevation; and

Fig 3 "is a rear elevation of the stand '35 and amplifier.

The receivernl is preferably of substantially flat circular form, 2 being its soundoutlet and 3 the diaphragm, and the remainder of its internalstructure being im- 40 material as far as the invention is concerned.

'- The other part -:of the combination comprises an amplifier 4, here shown in the form of a straight horn, and a holder 6, in which the receiver may be placed with its sound exit in communication with the small end of the amplifier. Such holder preferably con sists of an open shallow horizontal cup secured upon'the upturned small end 5 of the horn. This end passes through the bottom of the cup, to form a projecting rim 8, which meets the face of the receiver around the sound exit, in order to prevent the escape of sound waves from between the receiver and the amplifier when the receiver isin place. A foot 7 united to the small end of he horn or to thecup, or .toboth, steadies the amplifier and cup in their substantially horizontal positions. The axis of the amplifying horn, it may be noted, is preferably inclined somewhat upward.

While the foregoing is a preferred and simple embodiment of the invention, it will be understood that numerous changes may be made, as for example in respect to the nature and form of the amplifier and receiver holder and their mode of support,

without departing from essentials.

What I claimas new is:

A device for use in connection with a telephone receiver comprising a substantially horizontal horn having its small end upturned, a cup upon said upturned end, and a foot at said end projecting below the bend and laterally for supporting and steadying the horn and cup at the rear, the device being supported forwardly of the foot by the horn itself resting upon the underlying surface.
